The ESPHome 8-Zone HVAC Controller is a smart relay board designed specifically for controlling 24VAC HVAC dampers, irrigation valves, and other building automation devices.
Unlike typical relay boards that require DC power supplies and complicated wiring, this controller runs directly from a 24VAC transformer, making it perfect for HVAC and automation systems already using 24VAC control circuits.
Powered by an ESP32 microcontroller, the board runs ESPHome firmware, providing seamless integration with Home Assistant for full automation control.
With 8 relay outputs, the controller allows you to automate airflow zones, irrigation valves, or other 24VAC devices directly from your smart home system.
